Learning Outcomes
At the end of the course, students will be able to:
1. demonstrate knowledge and understanding of aspects of Physics of speech, including production of sound, amplitude vibration, sine waves, simple harmonic motion and physical properties of vibrating systems;
2. describe modes of vibration and its significance in voice identification;
3. learn the causes and investigation of vehicular accidents;
4. demonstrate knowledge and understanding of aspects of automobile accidents, including sources of information, eye witnesses’ accounts, tire and other marks, speed and damage, time and distance, reaction time, pedestrian impacts and vehicle condition;
5. demonstrate knowledge and understanding of elements of forensic photography such as types of cameras and films, digital photo imaging, Exposure Index, ISO number, photo imaging evidence, surveillance photography, aerial photography and methods for developing photographs; and,
6. describe legal aspects of visual evidence, photography of fingerprints, impressions and tool marks.
